For years, Blue Water Navy veterans were shut out of the Agent Orange presumption. A 2019 law reopened the door for offshore service.

For decades, the VA drew a hard line on Agent Orange. Veterans who set foot in Vietnam or served on its inland waterways, the Brown Water Navy, received the presumption. Veterans who served offshore on ships, the Blue Water Navy, did not, even though the same herbicides reached the coastal waters. The Blue Water Navy Vietnam Veterans Act of 2019 corrected this. It extended the Agent Orange presumption to veterans who served in the offshore waters of Vietnam.

If you served aboard a ship in the covered offshore area and have an Agent Orange condition, you now qualify for the presumption. This guide explains the offshore rule, the covered conditions, and how to file or refile.


What changed for Blue Water Navy

Before 2019, the VA required boots on the ground or service on inland waterways for the Agent Orange presumption. The Blue Water Navy Vietnam Veterans Act extended the presumption to veterans who served in the offshore waters of Vietnam, recognizing that the herbicides reached those waters. This restored access for a large group of Navy veterans who had been excluded.


The offshore distance rule

The presumption applies to service in the offshore waters within a defined distance of the Vietnam coast, generally set at twelve nautical miles. If your ship operated within that offshore zone during the qualifying period, you meet the location requirement for the presumption, without needing to prove you went ashore.


Who qualifies

Blue Water Navy veterans who served aboard ships operating in the covered offshore waters of Vietnam during the qualifying Vietnam era dates qualify. Your service records and your ship's deck logs or history can establish that your vessel operated within the covered area during the covered time.


Covered conditions

The presumptive conditions are the same Agent Orange conditions that apply to other exposed veterans. These broadly include several cancers, ischemic heart disease, type 2 diabetes, Parkinson disease, peripheral neuropathy, and hypertension, among others. If you have one of these and qualifying offshore service, the claim is presumptive.


No nexus needed

As with all Agent Orange presumptive claims, you do not have to prove the herbicide caused your condition. You establish qualifying offshore service and a current diagnosis of a listed condition, and the VA presumes the connection. The 2019 law made this available to Blue Water Navy veterans on the same terms.


What you need to show

  • Proof that your ship operated in the covered offshore waters during the qualifying period
  • A current diagnosis of an Agent Orange presumptive condition
  • Service records and, where needed, ship deck logs or histories
  • Medical records documenting the condition


Refiling old denials

Many Blue Water Navy veterans were denied before 2019 precisely because they served offshore. If you were denied for that reason, refiling under the current rule can result in a grant. This is one of the clearest cases where an old denial no longer reflects the law, so reopening the claim is well worth it.


Effective dates

Effective dates for Blue Water Navy claims can reach back in certain situations, particularly where you filed earlier and were denied only because of the offshore exclusion. Because the timing rules are specific, confirm the earliest date your history supports rather than accepting a later one by default.


Where to go from here

Confirm your ship operated in the covered offshore waters, match your condition to the Agent Orange list, and file or refile with your service records. Check the effective date for possible back pay.

Filing tip. A secondary claim rises or falls on the nexus. Name the service connected condition that is the cause, and get a provider to state the link in plain medical language using the at least as likely as not standard.
